Sambo

Sambo is a modern martial art, combat sport and self-defense system developed in the former Soviet Union, and recognized as an official sport by the USSR All-Union Sports Committee in 1938.
According to the International Federation of Associated Wrestling Styles (FILA), Sambo is one of the four main forms of amateur competitive wrestling practiced internationally today, the other three being Greco-Roman wrestling, Freestyle wrestling and Judo.

In 1980, Sambo was a demonstration sport at the Olympic Games in Moscow, Russia. However, due to boycotts, it failed to bring sufficient numbers for continued inclusion as a participatory game.
There is no single recognized founder of Sambo.
